摘要

针对聚对苯二甲酸乙二醇酯(PET)冷却结晶速度缓慢、加工周期长的问题，设计并合成了3种具有不同取代基的苯并咪唑类衍生物：2

2'-二苯并咪唑(2

2'-BBI)、2-苯基苯并咪唑(2-PBI)与2-氨基苯并咪唑(2-ABI)，并将其作为异相成核剂引入PET基体中。结晶动力学与微观形貌分析表明，3种成核剂的引入均能显著加速PET的结晶过程。其中，2-ABI展现出最优异的改性效果：当添加量为1.0 wt%时，PET复合材料的结晶峰值温度与结晶度分别跃升至213.5 ℃和29.8%。原位变温红外光谱进一步阐明了其微观诱导机制：2-ABI侧链的伯胺基团(－NH

)与PET骨架中的羰基(C＝O)在界面处形成了强烈的动态氢键网络，导致羰基特征吸收峰发生7 cm

−1

的显著红移。这种强界面相互作用有效降低了热力学成核能垒，协同驱动了大分子链向规整反式构象的快速排布与晶格固化。

Abstract

Addressing t

he issues of slow cooling crystallization rate and long processing cycle of poly(ethylene terephthalate) (PET)

this study designed and synthesized three benzimidazole derivatives with different substituents: 2

2'-bibenzimidazole (2

2'-BBI)

2-phenylbenzimidazole (2-PBI)

and 2-aminobenzimidazole (2-ABI)

which were introduced into the PET matrix as heterogeneous nucleating agents. Crystallization kinetics and morphological analyses show that the incorporation of all three nucleating agents significantly accelerates the crystallization process of PET. Among them

2-ABI exhibits the best modification efficiency: at an addition level of 1.0 wt%

the crystallization peak temperature and crystallinity of the PET composite increase dramatically to 213.5 ℃ and 29.8%

respectively.

In situ

temperature-dependent FTIR spectroscopy further elucidates the underlying induction mechanism: the primary amine groups (－NH

) on the side chain of 2-ABI form a strong dynamic hydrogen-bonding network with the carbonyl groups (C＝O) in the PET backbone at the interface

resulting in a significant red shift of 7 cm

−1

for the characteristic carbonyl absorption peak. This strong interfacial interaction effectively lowers the thermodynamic nucleation barrier and synergistically drives the rapid ordering of polymer chains into regular trans-conformations and subsequent lattice solidification.
